The U.S. Government acquired Franklin Island in 1806 and completed construction of the Franklin Island Light in 1808. This was the third lighthouse built in Maine. The U.S. Lighthouse Service and its successor, the U.S. Coast Guard, continued to staff the lighthouse for 160 years before the station was automated in 1967. The U.S. Fish and Wildlife Service acquired Franklin Island in 1973, making this the first island acquired for the Petit Manan National Wildlife Refuge Complex.

Franklin Island once supported one of the largest common eider colonies in Maine. The eider colony was decimated by avian cholera in the mid-1980s. The population has slowly recovered, and a 2003 survey documented over 330 pairs of eiders and over 100 pairs of great black-backed and herring gulls.

Franklin Island is closed to public use during the seabird nesting season: April–August. It is open during daylight hours the rest of the year.
